Get matched with top tankless water heater installers in Woodinville, WA

"George was super helpful over the phone determining the right water heating solution for our home, was highly communicative and transparent throughout the process, and made quick work of the installation of our electric water heater. Would highly recommend to other folks in Seattle in need of a water heater upgrade!"

"My water heater started leaking and my hot water was gone. I got an outrageous quote from a local plumber who was too busy too replace it. Thankfully I was able to contact George, and he was able to come the same day to replace it. Not to mention his prices were much affordable. I would highly recommend anyone who needs their water heater serviced!"

"Austin with Twin Water Heater did an amazing job converting our traditional tank water heater to a tankless system. He was knowledgeable, professional, and took the time to explain the entire process and answer all of our questions. The installation was clean and everything turned out great. I especially appreciated how transparent he was about the work that needed to be done and the cost—there were no surprises or pressure to add anything unnecessary. You can tell he really cares about doing the job correctly and making sure his customers are happy with the end result. We’ve been loving the tankless system and having endless hot water! I would absolutely recommend Austin and Twin Water Heater to anyone looking for a water heater installation or tankless conversion."

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"Great communication throughout the entire process, informative friendly people from the office to the field. All safety precautions were taken during both the in home estimate and final installation of the water heater which was completed in under 4 hours. SeaTown are my new best friends!"

"Mark was able to replace my water heater quickly and efficiently and went the extra mile to make sure I understood the function of the heater and the water leak gauge -- my old one was improperly installed and submerged by water (super helpful. not.) On a follow-up call he even turned me on to a trusted electrician, cuz I need a bathroom ceiling fan installed. Two thumbs up!!"

"Brian was on time and super knowledgeable for dealing with my tankless hot water heater. He got right to work and dealt with the problem and helped me establish a paper trail with the manufacture in case of any future warranty concerns."

"Plumbing Technician Dennis Poznyur did an outstanding job shutting/capping off a natural gas line servicing a gas dual fuel range in preparation for installing an induction range. Kudos to Dennis for very professional service."

"Installation went smoothly once the particular part we needed arrived. We were impressed by the care Devon took to consider our scheduling needs so that patient care wouldn't be interrupted during installation. He also made sure to install a mixing valve that prevents the water from being too hot for our young patients."

"I have used this plumber for over 4 years now - they respond immediately to any concern, are the most honest and fair people out there! Anything from simple drain clear, or water heater install, to a side sewer and complete DADU plumbing installation…they do it all, and with great communication! I pass their name and number to anyone who is looking for an honest and reliable plumber!"
